Try this:

{
	USB_DEVICE(0x0582, 0x014d),
	.driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) {
		/* .vendor_name = "BOSS", */
		/* .product_name = "GT-100", */
		.ifnum = QUIRK_ANY_INTERFACE,
		.type = QUIRK_COMPOSITE,
		.data = (const struct snd_usb_audio_quirk[]) {
			{
				.ifnum = 1,
				.type = QUIRK_AUDIO_STANDARD_INTERFACE
			},
			{
				.ifnum = 2,
				.type = QUIRK_AUDIO_STANDARD_INTERFACE
			},
			{
				.ifnum = 3,
				.type = QUIRK_MIDI_FIXED_ENDPOINT,
				.data = & (const struct snd_usb_midi_endpoint_info) {
					.out_cables = 0x0001,
					.in_cables  = 0x0001
				}
			},
			{
				.ifnum = -1
			}
		}
	}
},
